e. abscess interconnection degree

Personal care product of the present invention and/or dissolvable solid substrates have the abscess interconnection degree of height, are mainly perforate solid foams, rather than are mainly closed pore solid foam.Abscess interconnection degree can be evaluated by optical microscopy, scanning electron microscopy, micro-Computed tomography parameter (celestial body amasss and SMI index), gas survey proportion parameter (perforate %) or other suitable method.

The quantitative approach of measuring abscess interconnection degree is via optical microscopy.This can be by using shears or sharp blade, in the z-direction of measuring, cut wide rectangular of 2-3mm on described personal care product and/or described dissolvable solid substrates x-y maximum orthogonality surface, and the rectangular inside foam structure that turn 90 degrees to expose the transverse cross-sectional area of firm cutting of gained is carried out.Can pass through closely visual observation, or more accurate, by using and amplify as derived under the SZX12 stereoscopic microscope of Olympus Olympus America Inc. (Center Valley, PA) at stereoscopic microscope, evaluate this transverse cross-sectional area.Perforate personal care product of the present invention and/or dissolvable solid substrates are easy to identify by the interior section of inspection transverse cross-sectional area, described transverse cross-sectional area is mainly three-dimensional pillar network by comprising, comprise the third dimension along cross-sectional depth, described pillar has the unlimited void space of interconnection each other around.On the contrary, by being used to form the cutting process of the transverse cross-sectional area of exposure, the internal cross section of closed-cell foam will be rendered as the discrete bubbles being cut open, and only in the cross-sectional surface of bidimensional, interconnects.

The another kind of method of measuring abscess interconnection degree is and structural model index long-pending via celestial body.Use micro-computed tomography system (μ CT80, SN 06071200, Scanco Medical AG), the about 4cm of sweep diameter and high 3 to 7mm plate-like sample.Make the imaging when lying in cylindrical tube bottom of each sample.Image acquisition parameter is 45kVp, 177 μ A, 51.2mm visual field, 800ms integrating time, 1000 projections.Regulate number of leaves with Covering samples height.Data reconstruction group comprises great amount of images, and the pixel of each is 2048 * 2048, and isotropic imaging resolution is 25 μ m.With regard to data analysis, select to be positioned at completely the concerned volume of sample, avoid surf zone.Typical concerned volume is 1028 * 772 * 98 voxels.

Adopt the bone trabecula morphometry rating method of the Scanco Medical that threshold value is 17 to measure structural model index (SMI).With this index quantize bone trabecular structure outward appearance (referring to T.Hildebrand, the Quantification of bone microarchitecture with the structure model index.Comp Meth Biomech Biomed Eng of P.R ü egsegger 1997; The 1st volume: 15 to 23 pages).On orthogonal direction, minute quantity is stretched in trigonometric ratio surface, and calculate surface and the volume of area of new bone.Thus, can determine the difference quotient (dBS/dr) of bone surface.Then by following formulate SMI:

$\mathrm{SMI}=6\·\frac{\mathrm{BV}\·\frac{\mathrm{dBS}}{\mathrm{dr}}}{{\mathrm{BS}}^2}$

SMI relates to the protruding rate of structure to types of models.The SMI that the plate of desirable (flat) has is 0 (it is unchanged that plate stretches lower surface), and the SMI that desirable cylindric bar has is 3 (bar stretches the linear increase of lower surface).The SMI that ball has is 4.Concave structure has negative dBS/dr, obtains negative SMI value.The artificial boundary of concerned volume edge is not included in calculating, therefore by its elimination.

Except Scanco Medical analyzes, also carry out star cubing.Celestial body is long-pending is the measuring of space space opening degree in two phase structure.By pay close attention to mutually in (under the situation at us, it is background) select random equally distributed series of points, we can with random direction from these point in each extend straight line.Described straight-line extension, until their contact prospect phases.Then record in these straight lines the length of each.In each direction, (x/y/z) gets 10 random some samples, and selects 10 random angles at each some place.If straight-line extension to the border of concerned ROI, discards described straight line (we only wish to accept and the mutually actual crossing straight line of prospect).The achievement in research of final formula based on announcing in " Star volume in bone research ", A histomorphometric analysis of trabecular bone structure using vertical sections; Vesterby, A.; Anat Rec.; In February, 1993; 235 (2) volumes: 325 to 334 pages.

Wherein " dist " is individual distance, and N is studied straight line number.

Via gas hydrometry, measure perforate percentage composition.Gas hydrometry is to use the common analytical technology of gas displacement method Accurate Measurement volume.Use noble gas if helium or nitrogen are as replacement media.Sample is sealed in the device compartment of known volume, imports suitable noble gas, be then expanded to another accurate internal volume.Measure the pressure before and after expanding, and for calculating sample volume.This volume, divided by sample weight, is drawn to gas displacement density.

ASTM standard method of test D2856 adopts older air contrast proportion instrument model, and the method for measuring perforate percentage ratio is provided.This device is no longer produced.Yet, by enforcement, adopting the test of the AccuPyc gravimeter of Micromeritics, you can facilitate and accurately measure perforate percentage ratio.ASTM method D2856 has described for measuring 5 kinds of methods (A, B, C, D and E) of foamed materials perforate percentage ratio.

With regard to these experiments, can, by using nitrogen and ASTM foampyc software, adopt Accupyc1340 to carry out analyzing samples.Method C in ASTM method is used for calculating perforate percentage ratio.The method compares with the true volume being recorded by Accupyc adopting thickness and normal volume to calculate the geometric volume recording simply.Recommendation is by Micromeretics Analytical Services, and Inc. (One Micromeritics Dr, Suite 200, Norcross, GA 30093) implements these mensuration.The more information that technology is relevant is therewith found in Micromeretics Analytical Services website (www.particletesting.com or www.micromeritics.com), or is published in the books " Analytical Methods in Fine particle Technology " of Clyde Orr and Paul Webb.

f. cell wall thickness

The cell wall thickness of described personal care product and/or described dissolvable solid substrates is calculated from scanogram by micro-computed tomography (CT) system (μ CT80, SN 06071200, Scanco Medical AG) as described herein.According to adopting the bone trabecula morphometry rating method of Scanco Medical to measure the determined method of bone trabecula thickness, measure cell wall thickness.As the bone trabecula thickness definition obtaining from Scanco User handbook: bone trabecula thickness is used Euclidean Distance Transform (EDM), described Euclidean Distance Transform calculate from any point of prospect to nearest background dot Euclidean distance.The twice of the center line value that the representative of bone trabecula thickness measurement is associated with EDM local maximum, the representative of EDM local maximum is apart from the distance (twice of this distance will obtain thickness) of object central authorities.

g. specific surface area

The specific surface area of described personal care product and/or described dissolvable solid substrates is measured by gas-adsorption technique.Surface area is the measuring of solid sample exposed surface of molecular level.BET (Brunauer, Emmet and Teller) theory is for measuring the Epidemic model of surface area, and it is based on Adsorption Isotherms.Gas absorption adopts physical absorption and capillary condensation to carry out mensurated gas composition adsorption isotherm.Described technology is summarized with the following step: sample is placed in to sample tube and under vacuum or mobile air heating to remove the pollution in described sample surface.By deduct the weight of sky sample tube from degassed sample+sample tube weight, obtain sample weight.Then sample tube is placed on to analysis port, and starts to analyze.The first step in analytical method is that sample tube is emptying, then under liquid nitrogen temperature, uses helium, measures the free space volumes of sample tube.Then sample is emptying for the second time, to remove helium.Then instrument quantitatively adds krypton-85 gas by the interval with user appointment, until reach required pressure, measures, and starts to gather adsorption isotherm.

Sample preparation (degassed): the sample that there is no fully to remove institute's adsorption fouling thing will be degassed during analyzing, and a part of surface will not be used to mensuration.Degassed object is before analysis, from sample surface, to remove the molecule of these absorption.Absorption molecule must arrive all parts on described surface, to represent real surface area.By heating described sample, simultaneously that sample tube is emptying, prepare sample.

With regard to these experiments, by sample emptying degassed spending the night at room temperature.Then can use ASAP2420 and Krypton absorption, analyzing samples.Krypton is more preferred than nitrogen, because its saturation pressure is approximately 1/300 (Krypton: 2.5 holders of atmosphere under liquid nitrogen temperature; Nitrogen: 760 holders).Therefore, compare with nitrogen, under same relative pressure, in the free space of sample top, have the nitrogen molecule of about Krypton molecular number 1/300.Because Krypton and the nitrogen molecule of the roughly the same number of needs forms monolayer, so this number represents in the ratio nitrogen situation of institute's addition large many.Can pass through Micromeretics Analytical Services, Inc. (One Micromeritics Dr, Suite 200, Norcross, GA 30093) implements these mensuration.The more information that technology is relevant is therewith found in Micromeretics Analytical Services website (www.particletesting.com or www.micromeritics.com), or is published in the books " Analytical Methods in Fine particle Technology " of Clyde Orr and Paul Webb.
